Hi, I have made one vccs on breadboard and which is working. But I have a problem with the circuit. Actually I want to source and sink +/- 100 mAmp through a load of 500 ohm. My circuit is unable to draw that current. How can I modify for my requirement? I am attaching the circuit...
If I add diode for crossover distortion as in class AB amplifiers, then that 390 ohm cab be removed as shown in the image ?

Hi, I am attaching a image for volt to current converter. I found it on some old thread here only.It looks like howland circuit with push-pull amplifier. My question: opamp o/p going to base of transistors. Emitter are shorted and we take output from there. Whether 390 ohm resistor which is...
Re: bi-directional current source
I was trying to replicate the circuit as I need to build a bidirectional current source. I have a small doubt regarding one connection. Op-amp output goes to base of both transistors. Both emitters are shorted but they are not connected to 390 ohm resistor...
